Hi
The HUBER name is not an uncommon one in the UK records - nor are the forenames - which in german could be recorded as: Johan, Johannes, Frederic, Frederich, Friedrich etc.
Move the search to the US and the name is even more common,
(A family in New Orleans for example):
http://familytreemaker.genealogy.com/users/r/i/e/Virginia-S-Riecke/GENE1-0004.htmlThe Hamburg passenger lists have many possibilities. And no way of knowing which one might be yours.
I have noticed a researcher looking for John Frederick HUBER in US message boards, saying that his one was from Austria, near the German Border - which could be the Bavarian border.
John was in Ireland getting married by 1893. Do you have him in 1891 anywhere in England. Or Rosina? How do you know that the family of brothers left Germany between 1880 and 1914 - and aside from John, went to Philadelphia?
The German Military Record may be very useful and quite possibily your one way of finding more of your John Frederick Huber's family background & his siblings - could you perhaps scan and post it onto Rootschat (in parts at a time) for translation?
